摘要： An internal combustion engine, including a main combustion chamber serving as a main combustion chamber, an auxiliary combustion chamber adjacent to the main combustion chamber and smaller in capacity than the main combustion chamber, and a partition wall between the main combustion chamber and the auxiliary combustion chamber, the partition wall including an injection hole by which the main combustion chamber and the auxiliary combustion chamber communicate. A fuel supply device supplies fuel to the main combustion chamber and the auxiliary combustion chamber. A mixture forming device forms a mixture of air and the supplied fuel in the main combustion chamber, away from the partition wall before ignition. An ignition device ignites the fuel in the auxiliary combustion chamber, propelling an ejecting torch flame into the mixture of air and fuel in the main combustion chamber through the injection hole, thereby burning the mixture of air and fuel in the main combustion chamber.

摘要： A spark-ignition type internal combustion engine, including a main tank for storing a to-be-determined fuel having an unknown self-ignition property, an auxiliary tank for accumulating a reference fuel having a known self-ignition property, and a controller. The controller is programmed to supply to a combustion chamber a blended fuel prepared by blending the to-be-determined fuel and the reference fuel at a predetermined ratio, measure a self-ignition property of the blended fuel, and determine the unknown self-ignition property of the to-be-determined fuel based on the measured self-ignition property of the blended fuel, the known self-ignition property of the reference fuel and the ratio of the blended fuel. The controller is also programmed to introduce the to-be-determined fuel after the determination from the main tank to the auxiliary tank, and store the to-be-determined fuel in the auxiliary tank such that the to-be-determined fuel serves as a next reference fuel having a known self-ignition property.

摘要： An internal combustion engine includes neighboring main and auxiliary combustion chambers that are separated by a partition wall including a communicating passage. Ignition of an air/fuel mixture in the auxiliary combustion chamber produces a fuel torch that is jetted into an air/fuel mixture in the main combustion chamber. Under a predetermined operation condition, timing for opening an intake valve is retarded relative to both the timing for closing an exhaust valve and the timing for top dead center of a piston on an exhaust stroke. By retarding the timing for opening the intake valve, residual gas in the auxiliary combustion that is left over from a previous cycle can be reduced.

摘要： In an exhaust path, a HC trapping material which traps HC contained in exhaust gas temporarily, a H2O trap which traps H2O contained in exhaust gas and a CO oxidation catalyst are arranged in this order from the upstream side, wherein the H2O trap is disposed just upstream of and close to the CO oxidation catalyst. H2O and HC which are components disturbing the activity of the CO oxidation catalyst can be removed efficiently and the adsorption heat and condensation heat of H2O can be efficiently utilized to raise the temperature of the CO oxidation catalyst so that early activation of the CO oxidation catalyst is accomplished just after an engine starts.
